Manager Slot has transformed Gravenberch into one of the finest players in the Premier League, and he has revealed his delight at working under his countryman at Anfield.
He said: "I just feel good in my skin, to be honest. But does that have a reason? Yeah, things are going well at the club. I'm just doing my thing, and it's working out well now.
"He (Slot) gives me confidence now. He just lets me start in the lineup. It's going pretty well.
"As a player, you obviously want to get minutes. For me, that confidence is part of it. With that confidence, I feel more comfortable, and with the minutes, it keeps getting better."
Gravenberch added: "He's a good coach. He knows what he wants. He has a clear plan. Yeah, so far, we're executing it really well. Clarity from the start is always nice for me."
Pundit Joleon Lescott, meanwhile, has claimed he is one of the best midfielders in the world, adding: "There's an argument for it. His contributions, his goals and assists. He's been in a title-winning team. He's been the best No. 6 in the league. He was arguably their best player last year.
"He should definitely be considered. If you're one of the best in any position in the Premier League, then you're going to be considered the best in the world."
